Data types
REANALYSIS:
ERA-15
- reanalyses from 12/1978 to 02/1994
- spectral T106 resolution with 31 vertical hybrid levels
ERA-40
- reanalyses from mid-1957 to 2001
- T159 spectral resolution with 60 vertical levels
ERA-interim
- reanalyses from 01/1979 up to 3 months ago
- T255 spectral resolution with 60 vertical levels
- corrected for different models so should be consistent
- useful for long term analyses
FORECAST:
Operational data - data up to 2 days ago
DATA FORMAT:
- GRIB1
- GRIB2 was implemented on 18 May 2011.
